8×8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller. 8×8 LED Matrix module have many applications in real life, such as ...

So we can use a simple formula for routine calculations: “level = 255/5 x effective voltage” The experimental code for ATtiny85 is the same as the Arduino Sketch, as indicated. The only deviation is ...

Planning another Arduino build? If you’re just doing something simple like switching a relay or powering a LED, you might want to think about the Digispark. It’s a very small ATtiny-based ...

Most of us have an 8x8 LED matrix from one of our Arduino kits. What can we do with them? This module investigates how to use these interesting devices. Along the way, we describe a fun electronics ...

Power LED and Test/Status LED (on Pin0). – Size: 1.8cm x 2.6cm If you ever tried to get started with Arduino or the miniature ATTiny85 chip, you have found there is a learning curve with ...

Following on from getting an Arduino programme to run on an 8pin ATtiny (ATtiny85), I need to invoke the in-built brown-out reset circuit – because my application involves running from an ...

You youngins probably don’t remember this, but a few years ago there was an arms race on Kickstarter to create the smallest Arduino ... ATtiny85, with USB port, resistors, diodes, reset button ...

Related to being powered by a super capacitor, I also need to get my ATtiny to go to sleep ... As usual with Arduino, the ‘pin numbers’ aren’t the actual chip pin numbers, unless by coincidence. The ...

Maker and developers looking for a tiny Arduino development board might be interested in The Nanite 85, which could possibly be the world’s smallest ATtiny85 ... pin with the LED and the reset ...
